Aptus Startbooster Organic Root & Growth Stimulator – 250ml

£12.00
Unit price perEstimated delivery between September 19 and September 21.
A highly concentrated organic root and growth stimulator that supports vigorous root development, vegetative growth and beneficial microbial activity at just 2.5ml per 10L.
Aptus Startbooster is a 100% biological root and vegetative growth stimulator designed to help plants establish a strong, active root system and healthy vegetative structure. Its concentrated formula combines organic nitrogen chelated with L-amino acids, beneficial microlife biomass, humic acid from Leonardite and high-grade fulvic acid.
Startbooster works both around the root zone and within the plant. It encourages root and root-hair development while supporting stems and vegetative plant tissue, helping crops establish the structure they need before moving into active flowering.
The L-amino acids provide organic nitrogen and biostimulation while supporting beneficial bacterial populations. Microlife biomass helps break down nutrients around the roots, while humic acid supports water retention, root-zone conditioning and nutrient exchange.
With a standard application rate of only 2.5ml per 10 litres, Startbooster is extremely concentrated. A 250ml bottle provides enough concentrate to prepare approximately 1,000 litres of nutrient solution at the normal feeding rate.
Why choose Aptus Startbooster?
- Powerful root & growth stimulator – designed to encourage vigorous root development and vegetative growth.
- 100% biological formulation – made with active organic ingredients.
- Encourages root-hair development – supports the formation of an active root system during establishment.
- Supports stems & plant tissue – helps build strong vegetative structure before active flowering.
- Organic nitrogen with L-amino acids – combines organic nitrogen nutrition with amino-acid biostimulation.
- Beneficial microlife biomass – supports microbial populations and nutrient breakdown around the root zone.
- Humic acid from Leonardite – supports water retention, root-zone conditioning and cation and anion exchange.
- High-grade fulvic acid – included as part of the concentrated biological formulation.
- Highly concentrated – standard feeding requires just 2.5ml per 10L.
- Excellent coverage – a 250ml bottle treats approximately 1,000L at the standard rate.
What is Aptus Startbooster suitable for?
Startbooster is primarily designed for propagation, establishment and vegetative development. These are the stages when establishing a healthy root system and strong vegetative structure is particularly important.
During normal crop feeding, use Startbooster throughout vegetative growth alongside an appropriate NPK fertiliser. The Aptus UK programme also carries Startbooster into early flowering for the first watering only, after which it is withdrawn as the crop moves into active flowering.
Startbooster also has dedicated applications for new clones and transplant establishment. Aptus specifies different concentrations for these uses, allowing the same product to support crops from propagation through established vegetative growth.
It can be incorporated into a complete Aptus feeding programme or used alongside another suitable liquid NPK base fertiliser. On pre-fertilised growing media, Aptus also allows Startbooster to be used without an additional vegetative fertiliser where sufficient base nutrition is already present.
How to use Aptus Startbooster
For normal feeding, use 2.5ml of Startbooster per 10 litres of water, equivalent to 0.25ml/L or a 1:4000 dilution. Use throughout vegetative development and for the first watering as the crop enters early flowering.
For 10L of nutrient solution, use 2.5ml. For 50L, use 12.5ml. For 100L, use 25ml. For a 500L reservoir, use 125ml. For 1,000L, use 250ml.
At the standard 0.25ml/L rate, a 250ml bottle prepares approximately 1,000 litres of nutrient solution.
When preparing the nutrient solution, add the NPK base nutrients first and measure the EC. Add Startbooster afterwards and mix thoroughly.
For new clones, Aptus recommends a separate dilution of 1ml per litre of water. This is a propagation-specific application rather than the normal reservoir feeding rate.
For transplanting, Aptus recommends dipping the roots in a solution containing 10ml per litre of water. This stronger concentration is specifically intended as a transplant root dip.
Startbooster is an organic product. Do not leave mixed Startbooster standing in a reservoir for longer than 2 – 3 days, as biological activity can contribute to organic biofilm and irrigation-line blockages.
When Startbooster is applied through drip irrigation, use Aptus System-Clean alongside it to help manage organic build-up and keep drippers and irrigation lines clear.

Aptus Startbooster FAQs
Is Aptus Startbooster organic?
Aptus describes Startbooster as a 100% biological product made with active organic ingredients.
What is in Aptus Startbooster?
Startbooster contains organic nitrogen chelated with L-amino acids, microlife biomass from controlled fermentation of selected beneficial strains, humic acid from Leonardite and high-grade fulvic acid.
What does Aptus Startbooster do?
Startbooster encourages root and root-hair development while supporting stems and vegetative plant tissue. Its biological components also support microbial populations and nutrient availability around the root zone.
How much Aptus Startbooster should I use?
For normal feeding, use 2.5ml per 10 litres of water. This is equivalent to 0.25ml/L or a dilution of 1:4000.
How much Startbooster do I need for 50 litres?
Use 12.5ml of Aptus Startbooster for 50 litres of nutrient solution.
How much Startbooster do I need for 100 litres?
Use 25ml of Startbooster for a 100L reservoir at the standard rate.
How much Startbooster do I need for a 500L reservoir?
Use 125ml of Startbooster for a 500L reservoir at the standard application rate.
How much nutrient solution will 250ml of Aptus Startbooster make?
At the standard 0.25ml/L application rate, a 250ml bottle treats approximately 1,000 litres of nutrient solution.
When should I use Aptus Startbooster?
Use Startbooster during establishment and vegetative growth. Under the Aptus UK programme, it is also used for the first watering in early flowering before being withdrawn as the crop progresses further into bloom.
Can Aptus Startbooster be used for clones?
Yes. Aptus recommends a separate 1:1000 dilution for new clones, equivalent to 1ml of Startbooster per litre of water.
Can Aptus Startbooster be used when transplanting?
Yes. For transplanting, Aptus recommends dipping the roots in a 1:100 Startbooster solution, equivalent to 10ml per litre of water.
Is Aptus Startbooster a base nutrient?
No. Startbooster is a root and growth biostimulant. For normal crop feeding, use it alongside an appropriate NPK base fertiliser.
Can Startbooster be used with another brand of base nutrient?
Yes. The Aptus UK programme allows another suitable liquid NPK base fertiliser to be used, so Startbooster does not depend on Aptus All-in-One Liquid as the base feed.
Can Startbooster be used with pre-fertilised soil?
Yes. Aptus states that Startbooster can be used on pre-fertilised soil without an additional growth fertiliser where the growing medium already provides sufficient base nutrition.
When should Startbooster be added to the nutrient solution?
Add the NPK nutrients first and measure the EC. Add Startbooster afterwards and mix the solution thoroughly.
Can Aptus Startbooster be used in drip irrigation?
Yes, but because Startbooster is organic, Aptus recommends using System-Clean alongside it in drip irrigation systems to help manage organic build-up and blocked lines.
How long can mixed Startbooster stay in a reservoir?
Aptus recommends keeping Startbooster in a mixed reservoir for no longer than 2 – 3 days to reduce organic biofilm build-up and the risk of blocked irrigation lines.
What is the difference between Aptus Startbooster and Topbooster?
Startbooster focuses on roots, establishment and vegetative development. Topbooster is the Aptus bloom and maturation stimulator used once the crop moves further into flowering.
